On Thursday an official coroner’s report was released, pinpointing the cause of Whitney Houston’s death. The singer died of accidental drowning, which might’ve been the result of a heart attack, triggered by heart disease and the traces of cocaine found in her system. A full report is expected to surface in the upcoming weeks, which may include test results and detailed descriptions of Houston’s health status, determining whether or not the 48-year-old singer suffered from a heart attack on February 11.

The report is also expected to include toxicology details showing much cocaine remained in Houston’s system when she passed away.

Last week the L.A. County revealed that cocaine use and heart disease were contributing factors to Houston’s death. According to the report, traces of cocaine were found in her system at the time of death along with Xanax, Flexeril, marijuana and Benadryl, which officials said played no role in her death.

No cocaine was found in the singer's room when she died, but coroner spokesman Craig Harvey noted that cocaine metabolites were found in her system, leading them to conclude that Houston was a chronic user of the drug. A number of prescription pills were recovered in the Beverly Hills hotel room, but officials from the coroner's office said that there wasn't an unusual amount of medication.

Houston was laid to rest in her hometown of Newark, New Jersey, during an invite-only funeral service at the New Hope Baptist Church on February 18.
